CFLs flicker when Wall Swtich WS467 is OFF Jim Hewitt 03-05-08

Howdy,

I've been slowlyg trying CFLs in the house to see if they work OK wtih our
X10 installation. We've decided that the quality of light is acceptable for
the energy $ savings.

But, when I put some (N:Vision from Home Depot) 60W CFLs in the kids' room
overehad light, controlled by a WS467, everything was fine until I turned
the lights off. They don't go fully off! We get a very low light flicker,
probably 5-10 times a second. I triple-checked, the wall switch was not
dimming the lights.

Is this a result of the current sense (for local control)? If so, would the
standard mode for disabling current sense stop this?

It is doubtful that the kids would sleep well with this annyong flicker, but
also likely that it would also damage the CFL electronics eventually.

Thank you for any input. Or for pointing me to a more appropriate group.

Jim

The WS467 is a 2 wire device that requires continuous current
flow to operate. It normally gets this through the cold filament
of an incandescant lamp. Put a small incandescant lamp in
parallel with the CFL and the CFL will stop flickering. I'm
currently using a 15 watt lamp but I plan to try a 4 watt night
light.

Thanks, John. I'll give that a try. But the kids might still balk at a
night light in their room - they're way beyond that now. :-)

However that will be fine for the porch lights.

Yup, disable the current sensing (local control) and the lights will
stop flickering. Been there done that! :-)

Not quite! The WS467 is only a two-wire device. To disable the current
which causes the CFL flickering would remove power from the WS467
circuitry and prevent it from being turned on remotely. (The WS467 does
not have "local sensing" as the term is generally understood for plug-in
lamp modules.)

The OP needs to replace the WS467 with a wall switch designed for
fluorescent lamps. Note that these all require having a neutral wire in
the switchbox, and generally operate with a relay, so there will be an
audible click when they're turned on or off.
